Abstract
A system and method for state-based execution and recovery in a payment system is presented. A payment system uses a state machine to track completed sub-tasks using a state progress identifier and completion state data. When a failure occurs, stored completion state data and the state progress identifier indicate the last successfully completed sub-task. As such, when the payment system resumes payment operation execution after a failure, the state machine retrieves the stored completion state data and state progress identifier, and resumes execution based upon the retrieved information. As a result, the payment system continues payment operation execution at a point as to not duplicate the payment operation's previously completed sub-tasks.
